My 13 y/o is missing ten (yes, ten) permanent teeth. She's been in braces forever and we are looking toward dental implants when she is a few years older. However, I read where implants only last around15 years - is this true? Cost is definitely a factor since we have already spent a small fortune, so I am thinking bridge instead of the implants. Opinions?? Is there any other procedure we might consider? Thanks.
